Question

A dice
is rolled once.what is the probability of getting a prime number

Answer 1

Answer:1/2

Step-by-step explanation:

Prime number are the number which has only two factors including 1 and itself

Like 2 it will be divided by 1 and itself

Sample space (1 2 3 4 5 6)

N(s) = 6

Events are (2 3 5)

Note : 1 is not prime number because it has only one factor and that is itself 1

N(e) = 3

Probability = n(e)/n(s)

= 3/6 =1/2 answer
